Problem with Memory Addresses and Pointers

syron · February 10, 2008

Hi guys,

I'm pretty new to AutoIt. I was making a little tool for a game. It should read out the HP, MP and so on. I've got pointers and so on, but I dont really know how to put that into my script.

I attached a picture which shows what's the pointer and the offset, please help me to find out what do write in my script, I mean the 0xDATAS to get my script working. It works with those addresses which r generated when the game starts, but when I put the pointers / offset into my script it doesnt work!

On the screenshot u see the current hp stuff and in the script is the variable called $CurHpOffset.

Thanks in advantage!

#Include <Memory.au3>
Global $Pointer = 0x008F71DC
Global $CurHpOffset = 0x450
Global $CurMpOffset = 0x454
Global $CurEpOffset = 0x458
Global $CurSpOffset = 0x45C

    Global $DllInfo1 = _MemoryOpen($Process)
    $CurHpAdd = _FindNewAddress($Pointer, $CurHpOffset)
    $CurHp = _MemoryRead($CurHpAdd, $DllInfo1)

    Global $DllInfo1 = _MemoryOpen($Process)

Not sure why this would happen, but does the pointers change at any point whilst running the game?

syron · February 10, 2008

no, the pointer doesn't change. it always points me to the right address in CheatEngine, even if I restart the game

no, the pointer doesn't change. it always points me to the right address in CheatEngine, even if I restart the game

Ok. How does the following go for you? I played around a bit. For some reason I don't have _MemoryOpen () or _MemoryRead () so I can't even see if it works...

#include <Memory.au3>

Global $Pointer = 0x008F71DC

Is anything running that would block attempts to read the memory?

syron · February 10, 2008

well... u might can use it with _MemOpen / _MemRead and so on.

nope, nothing blocks it, cuz I disabled everything in the game exe

No I don't see it. What version AutoIt do you have installed?

syron · February 10, 2008

No I don't see it. What version AutoIt do you have installed?

AutoIt Version 3.

well I can easily give you the memory.au3, which I am using...

@syron

The UDF you call Memory.au3 is actually NomadMemory.au3. It might be better to rename it to avoid future confusion with Memory.au3 which is supplied with AutoIt.

The function you have to calculate the memory address is possibly the problem.

This is how I calculate the new memory address from the base address and an offset

Func AddrCalc($StartAddr, $Offset)
    Return '0x' & Hex(number($StartAddr) + $Offset, 8)
EndFunc

It looks unecessarily complicated but I've been using it for a long time with no problems.

BrettF · February 10, 2008

Ah. You should have said it wasn't an AutoIt include.

Does that mean, that I should replace the "_FindNewAddress" function with your "AddrCalc" function?

sry Im pretty new to working with addresses, hope you understand it.

and if I should replace it, could u show me how it should look like?

Yes. Just replace all contents of you func with the return line that was posted.

That's how it looks like now just replaced the code in the function. but it doesnt work :/ it should read out "1335" Hp and the msgbox gives me "16"

#Include <NomadMemory.au3>
Global $Pointer = 0x008F71DC
Global $CurHpOffset = 0x450
Global $CurMpOffset = 0x454
Global $CurEpOffset = 0x458
Global $CurSpOffset = 0x45C

HotKeySet("{F6}", "GetInfo")

While 1
WEnd

Func GetInfo()
    Global $Process = WinGetProcess("Element Client")
    
; HP Anzeige
    Global $DllInfo1 = _MemoryOpen($Process)
    $CurHpAdd = _FindNewAddress($Pointer, $CurHpOffset)
    $CurHp = _MemoryRead($CurHpAdd, $DllInfo1)
    _MemoryClose($Process)
    
    MsgBox(64, "Your character info:", "Your character`s hp: " & $CurHp)
EndFunc

Func _FindNewAddress($Pointer, $Oset)
    Return '0x' & Hex(number($Pointer) + $Oset, 8)

The memory address has to be the memory address pointed to by the pointer not the address of the pointer.

0x008F71DC is the address of the pointer, you want the contents.

Ah, now I see what your function was doing. Sorry I misunderstood.

Try doing this then

Func _FindNewAddress($Pointer, $Oset)
    Return '0x' & Hex(_MemoryRead($Pointer,$DllInfo1) + $Oset, 8)
EndFunc

well... it gives me 7929939 instead of 1335 :/

Take a look at the screenshot on my first post, could be there a problem of taking the addresses into the Autoit code?

Edited February 10, 2008 by syron

BrettF · February 10, 2008

Try make the offset a whole number maybe?

syron · February 10, 2008

you mean 0x00000450 instead of 0x450 ? Already tried it. No difference :/

MerkurAlex · February 10, 2008

Im also new to memory reading but couldnt you just use the _memoryreadpointer() function inside the NomadMemory.au3?

Seriously, if you have no clue about these things, you should just forget about it and do something else. This way will be safer for you and everyone else.

Or at least start from reading the documentation of that software (Cheat Engine?).

Because it's pretty obvious you aren't even familiar with that screenshot you posted, and it has nothing to do with AutoIt.

It's evident that you should read memory at 0x8f71dc to get the address of a pointer (0x52a31b0 in the example). Then read that memory to get the address of the data struct (0x51d4838 in the example). And only then add the offset 0x450 to read what you want to read.

yeah u r right, it was just a test, cuz I learned PHP with things like this... I had no clue about how to write e.g. some datas into tables and isn't there a sentence which a teacher gives a pupil? "Learning by doing" so that's how I learn stuff and I understand the complete code, the only problem is the thing in the CheatEngine which is absolutely new to me, but I figured out by myself how to get the pointers and so on...

but thanks for the information about the address of a pointer, ty

I keep getting this message (sometimes, sometimes not):

_WinAPI_WriteProcessMemory: Only part of a ReadProcessMemory Or

WriteProcessMemory request was completed.

It happens when _MemWrite is called in Memory.au3

Func _MemWrite(ByRef $tMemMap, $pSrce, $pDest = 0, $iSize = 0, $sSrce = "ptr")
    Local $iWritten

    If $pDest = 0 Then $pDest = DllStructGetData($tMemMap, "Mem")
    If $iSize = 0 Then $iSize = DllStructGetData($tMemMap, "Size")
    Return _WinAPI_WriteProcessMemory(DllStructGetData($tMemMap, "hProc"), $pDest, $pSrce, $iSize, $iWritten, $sSrce)
EndFunc   ;==>_MemWriteoÝ÷ Ø"¶l¢jnµêè®+-êÞj§z¶¥¦ºéëÞ®¯zg¦¢¼©®åzk0ØZ*-êé®+jk2ý´áÈ¬¶jYm«]¡ë-çZ¨jëh×6  _MemWrite ($struct_MemMap, $TextRange_ptr)

I have looked at $struct_MemMap and $TextRange_ptr just beforew the call and $struct_MemMap= "" (nothing) and $TextRange_ptr = 0x01FC1000.

Any ideas?
